Substitutional Si Doping of Graphene and Nanotubes through Ion Irradiation-Induced Vacancies
Low-dimensional materials have unique intrinsic properties as a result of their electronic wave-function confinement in one or two dimensions. For example, the electronic properties of single-walledExpand
Atomistic Understanding of Damage and Beam-driven Dynamics in 2D Materials
Transmission electron microscopy is a powerful probe of the chemical structure of materials. Due to efficient aberration correction, the capabilities of modern instruments have advanced so far thatExpand
Uncovering the Mechanism for Electron-beam Manipulation of Dopants in Silicon
Covalently bound impurity atoms in crystal lattices can be manipulated via the elastic backscattering of probe electrons from nuclei using the atomically focused electron irradiation of a scanningExpand
Minimal unitary (covariant) scattering theory
In the minimal three particle equations developed by Lindesay the two body input amplitude was an on shell relativistic generalization of the non-relativistic scattering model characterized by aExpand
